STEAM-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 354,987, dated December 28, 1886,

Application led February 20, 1886. Serial No. 192,737. (No model.)

To all whom it may concern.-A

Be it known that I, JOHN MclN'rvRE, of West Hoboken, in the countyv of Hudson and State of New Jersey, have invented a new and Improved Steam-Condenser, of which the following is a full, clear, and exact description.

My invention relates to certain improvements in surface-condensers of the Lighthall type, wherein water-pipes are used to effect the condensation of the steam; and my invention consists, principally, in dividing the pipes into nests or tiers by the intervention of plates that compel the steam to spread and circulate more perfectly among the pipes.

The invention also consists in forming chambers adjacent to the inlet and exhaust ports of the condenser; and, also, in providing the top and bottom plates which form said chambers with regulating-valves, by which the openings therein through which the steam passes to and from the spaces containing the tubes may be contracted or enlarged at any time to suit t-he pressure and to compel the air-pump to draw the uncondensed vapors from the interior of the condenser throughout the whole length of the pipes, thus preventing the formation of air-pockets and utilizing more perfectly and effectively the cooling-surfaces of the pipes.

The invention also consists of the construction, arrangement7 and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,"

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of my new andimproved condenser taken on the line x x of Fig. 2. Fig. 2 is a transverse sectional elevation taken on the line y y, Fig. l.

The condensing-chamber is inclosed by the side walls, a a, the top and bottom walls, b b', and the end walls, c c. Vithin the condenser are placed the water-pipes A A, and above the water-pipes is placed, a short distance from the wall b, the plate or partition d, which, together with the wall b, forms a chamber, B, to receive the steam from the induction-port C. A short distance above the lower wall. b', is placed within the condenser a horizontal plate or partition, f, which, together with said wall b', forms a chamber, D, from which the uncondensed vapors are pumped through the eduction-port E.

Between the partitions or plates d and f are placed the intermediate partitions or plates, g g g2, which divide the pipes A into several tiers or nests, as shown clearly in the drawings. The plate d has an opening,`d, at one side, which extends nearly the whole length of the condenser for the passage of steam from the chamber B to the chamber formed by the saidpartition d andthe next partition g below, and the partition g at the opposite side of the condenser is formedwith an opening, h, which extends nearly the whole length of the condenser for the passage of the steam to the next chamber below. The partition g is formed with an opening, h', on the opposite side of the condenser, which also extends nearly the whole length of the condenser for the passage of steam, and the partition g? is formed on the reverse side with an opening, hfor the passage of steam to the bottom pipechamber. From this latter chamber the steam passes through the opening f in thebottom partition, f, to the chamber D, from which it is exhausted by thev air-pump. In this manner the steam is given a circuitous course through the condenser, and is caused to circulate in contact with all ofthe cooling-surfaces of the tubes.

The opening d, while it may be of greater or less area, should be of about three times the area of the steam-inlet port in low-pressure cylinders.4 The passages h h l in theintermediate plates should be about five times the area of the steam-port in the cylinder.

Upon the upper surface lof the plate dis placed a valve, F, `for closing more or less the opening d. l This valve F may be operated by various means; 'but I prefer to employ the screw-rod F, which is connected at its inner end to the plate and works in a screw-threaded opening in the side wall of the condenser, and is provided at its outer end with a crank, j, so that by turning said crank the valve may be easily moved to regulate the passage of steam through the opening d', and upon the bottom partition is placed a valve, G, for closing the passage f. rllliis valve G is in all respects like the valve F, being arranged to be operated by a screw-rod, G, and crank k, and

enter the chamber D at one side after having passed in contact with all the pipes above the partition f, and the chamber Dis of sufficient depth not to choke the exhaust. If the plate 5 f were not used, the exhaust of vapors would be from the slot h2 down diagonally across the chamber of the condenser to the eduction-port E, so that the cooling effect of many of the pipes in said lower chamber would be lost, and 1o if the chamber D is not of sufeient depth the plate f would interfere with the exhaust; in other words, it would choke the action of the pump upon the interior of the condenser.

Having thus fully described my invention, 15 I claim as new and desire to secure by Letters Patent- Y Y In a condenser, the plate f, placed be JOHN MCINIYRE.
